Global O-Ring and Seal’s oil seal part numbers are designed to describe the seal size, style, and material composition. When searching for oil seals via our online store, you will not only be presented with your selection but with comparable oil seals of the same dimensions. There are often viable style substitutions that are functionally compatible but with additional features. With over 50,000 unique oil seals in our database, you can cross-reference 215,000 part numbers of OEMs and Manufacturers. In the Search Bar above, simply type the OEM/manufacturer part number alone (no need to type the name), and the oil seals matching that part number will be displayed.

Always start by making sure the oil seal is facing the right direction. The oil seal must be positioned with its spring to the side of the medium to be sealed. The oil seal must then be pressed into the bore. It must fit tightly (H8 in the groove is recommended). Use appropriate tools for this, such as an impact socket set, to ensure that the force is applied evenly during pressing. The oil seal must never be hammered into the bore with brute force, but eased in.
